Understanding the -4h Gap: Portugal vs Santiago
Portugal runs on Western European Summer Time (WEST) at UTC+01:00, currently observing daylight saving time. Santiago runs on Chile Summer Time (CLST) at UTC-03:00, also currently on daylight saving time. That puts Portugal 4 hours behind Santiago — a difference of -4h at the current offsets.
In practice, when it is 9:00 AM in Portugal it is 5:00 AM in Santiago. Midnight in Portugal is 8:00 PM in Santiago. Because both zones shift for daylight saving, the gap between them only changes during the few weeks each year when their transition dates differ.

Why people convert Portugal to Santiago time
- Scheduling a call from Portugal to Santiago: a 10:00 AM start in Portugal lands at 6:00 AM in Santiago, so you can confirm the slot without doing the arithmetic yourself.
- Finding shared working hours: both Portugal and Santiago are inside the 9-to-5 working day between 1:00 PM and 5:00 PM WEST time (9:00 AM–1:00 PM CLST). That is roughly 4 hours of usable overlap.
- Watching a live event or market open: Portugal viewers need 5:00 AM in Santiago to catch a 9:00 AM start there, and 4:00 AM if the event is anchored to Portugal.
- Always state the zone abbreviation, not just the hour. "3:00 PM WEST" is unambiguous; "3 PM" across a -4h gap is not.
- Block 1:00 PM–5:00 PM WEST as the recurring meeting window if you work primarily from Portugal and need Santiago colleagues present.
- Portugal: Clocks fall back on Sun, Oct 25, 2026. Re-check this page after that date because the offset changes and so does the -4h gap.
- Santiago: Clocks fall back on Sun, Apr 4, 2027. Any meeting series spanning that date will shift by an hour in local time.
